Summary
The Cooper Union
education university legacy
COOPERUNION is the network of The Cooper Union for the Advancement of Science and Art, the private college at 51 Astor Place in Manhattan's East Village.
What it's used for
- Campus networking for Cooper Union's schools of engineering, architecture and art: teaching, labs, student services and administration.
- Announces a small legacy allocation (a
/20plus a/24) — sized for a single-campus institution of a few thousand people.
Notable
- Reverse DNS across the space resolves under
cooper.edu, confirming the address block is used directly by the college rather than delegated out. - Cooper Union is unusual among US colleges for its history of full-tuition scholarships; its network is correspondingly small and self-run rather than outsourced.
Interesting
- The ARIN registration dates to the mid-1990s, placing Cooper Union among the earlier US colleges to run its own routed autonomous system rather than sit behind a regional network.

No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-20, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Spamhaus DROP
Not on ASN-DROP The network as a whole is not listed.
No DROP prefixes None of its announced space is on the DROP prefix list.
Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 442 networks and 1,778 prefixes, as published 2026-10-20. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.
FBI IC3
No IC3 indicators Nothing from the FBI IC3 feed.
IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
